There is no commonly agreed unit of measurement for transparency and accountability work. Many organisations actively work around the world to promote these principles, but there has been no effective way of knowing if that work produces results. Integrity Action has developed an approach that achieves results that can be measured through a ‘fix-rate’. The fix-rate measures the incidence with which transparency and accountability problems are resolved to the satisfaction of key stakeholders. Integrity Action’s Community Integrity Building approach has delivered a fix-rate of up to 80 percent in terms of improving the quality of roads, schools and public services for thousands of people. This working paper makes the case for the fix-rate as a key metric for work in this field and it outlines some of the implications of this approach for other transparency and accountability work.
